Title: Wire bonding structure
Inventor: KOMATSU IKUO
IPC: H01L21/60
Filed: 1988-12-29
Abstract: PURPOSE:To realize a bonding structure through a uniform pressure by relaxing concentration of a pressure a wedge against an aluminum wire through irregularities provided in a metal lead surface.

Filed: 1989-12-25
Abstract: PURPOSE:To improve the operation ratio of an information processor by carrying out an instruction subjected to one of two program counters at an idle part when this idle part is produced in a pipeline while an instruction subjected to the other program counter. CONSTITUTION:When a detection means 5 detects that an idle cycle is produced on a pipeline with the execution of an instruction given from a 1st program counter 1 while this instruction is processed by an arithmetic means 7 on the pipeline, a selector 6 selects and outputs an instruction given from a 2nd program counter 3.
